Find the number of bytes used by a UTF-8 character string
#include <utf8.h>
int utf8strnlen( char const *text,
int max_len,
int *num );
- text
- A UTF-8 string.
- max_len
- The maximum number of characters to count.
- num
- A pointer to a location where utf8strnlen() stores the
number of characters formed by the number of bytes occupied by
max_len characters in the string text.
This will be different from
max_len if there are fewer than max_len
UTF-8 characters in text.
ph
The utf8strnlen() function returns the number of bytes occupied by
max_len characters in the string text.
The number of bytes occupied by
max_len characters in the string text.
